Hi Rahul & Aravilli Thanks for the clarifications.
Rahul Can you please explain us the "Finite State Machine (FSM)" we are talking here? I notice three fsm tags, fsm_input.tag, fsm_confirm.tag and fsm_run.tag. When does this state machine start and what are the transition states it goes and what are its effects. Aravilli Seen the mails you forwarded. I have a question on the implementation "commenting the script element in the fsm_input.tag"; given. I did not find the "builtinGrammar.tag" in the rdc folder. Is this deprecated or the one you suggested and rdc is yet to yet to approve?

It is generally recommended to leave it unspecified, so the component submits back to itself which is its default behavior (and thus, allows its state machine to run to completion). The RDC framework in itself, does nothing for cross-page navigation. There are multiple web application frameworks that provide such controllers (such as Struts), and we encourage you to pick one of those while authoring your applications. To illustrate the point, the RDC distribution does provide tags to submit to Struts actions, and echo the errors from these actions as prompts. More on that here: http://wiki.apache.org/jakarta-taglibs/ReusableDialogComponents/Tutorial s/StrutsInterface If you want to directly submit to another JSP (without using Struts), that is quite easy as well, see my other note that Aravilli referenced earlier in this message thread. These two approaches maintain component boundaries and responsibilities appropriately. > Say to have something like > > <filled> > <submit next="UseCollectedAlpha.jsp" namelist="alphacollected var1 var2 > var3"/> > </filled> > > instead of > > <filled> > <script src="/rdc-examples/.grammar/nbest.js"/> > <var name="alphaResultNBest" expr="serializeNBest()"/> > <submit > next="/rdc-examples/alpha.jsp;jsessionid=CD6603360BFF6C0D33417D414A2D205 C" > method="post" namelist="alphaResultNBest"/> > </filled> > > is it possible to implement this? <snap/> Yes, as mentioned above. > whats the reason to send the confidence, > utterance and the interpretation as a serialized object from the nbest.js? > by default the maxNBest is set to 5 and all the values are concatenated and > returned. is there any special reason of such implementation, when i can > directly take up the "application.lastresult$.utterance" for the most > probable value, the asr recognized. > <snip/> A RDC component is a JSP tag, and exists server-side. The information you quote is only available on the client. The framework makes sure application.lastresult$ can be examined by the component's private data model (see Building Blocks for what that means): http://wiki.apache.org/jakarta-taglibs/ReusableDialogComponents/Tutorial s/BuildingBlocks > 2) how is a simple JSP with 4 lines of code getting translated to few tens > lines of code?

Each component maintains an internal finite state machine, which determines what output is generated at any given turn. > The config file gives the prompts list, this part is > understood.

The private data models are here: http://svn.apache.org/repos/asf/jakarta/taglibs/proper/rdc/trunk/src/org /apache/taglibs/rdc/ The methods of importance are validate() and canonicalize().
